When should I prune dieffenbachia?

Spring or early summer for best regrowth; avoid pruning in winter. Cut the main stem to the desired height just above a node using clean, gloved hands and sharp pruners. The remaining stump will sprout new side shoots. The removed top can be rooted in water or moist potting mix.

How often does dieffenbachia need pruning?

Every 2–3 years, or when the plant becomes too tall or leggy. Dieffenbachia grows tall and bare-stemmed over time. Prune to control height and encourage lower branching. The cut tip can be rooted as a cutting. Always wear gloves — the sap contains calcium oxalate crystals that cause intense mouth and skin irritation (the common name 'dumb cane' reflects this toxicity).
